I need to calculate Integral (F . dr), where F(x,y,z) = (z^2, xz, 2xy) and C is the curve obtained from the intersection of the surface z=1-y^2, when z>=0 and the plane 2x+3z=6. I'm trying that one for over 5 hours already...

wait why is that integral a vector? sorry I am just learning this stuff right now. I'm not even in vector calculus yet. just the basics from multivariable calc. I would like to see how to do this as well!

Over 8 hours trying to solve this problem, still nothing :(
Well, it's a vector integral because the integral is not over a scalar function, but over a vector field ... this stuff is complex. I'll have an exam tomorrow morning (my final) and I can see I'm completely screwed ...
